Definitions
- the field of the invention is that of intelligent portable objects such as a smart card or transponder, and more particularly the exchange of data by inductive coupling within such an object.
- the document EP0057602 describes an intelligent portable device for paying for services.
- This device comprises an integrated circuit chip, via a bus grouping together conductive wires, with other components of the device including an antenna, a display screen and an input keyboard.
- This document therefore does not provide that the internal components communicate exclusively via a contactless link with an external station.
- the document US6073855B describes an apparatus for receiving, maintaining and transmitting information and data.
- the device comprising a main computer and at least two cards in PCMCIA format, placed in parallel in a dedicated compartment.
- An interface allows communication between PCMCIA cards.
- the communication interface can divert data which normally must pass via a standard bus which physically connects the PCMCIA cards to the main computer in order to speed up the transmission of information and data, for example by capacitive, optical or inductive coupling. . Since it is a question of accelerating the rate of transfer, this document does not plan to replace the physical connection by a contactless link as for our GEM1024.
- Document US5537126 describes an information display system at a point of sale, using electronic display labels.
- the labels are in electromagnetic coupling with a conductor.
- a control circuit is used to generate an information signal which contains the address of the label and data.
- a modulator circuit transforms an alternating current into an information signal and applies it to the conductor for its transmission to the display labels.
- Each of the labels is equipped with an electromagnetic coil coupled to the conductor.
- Each display label is equipped with a manual initialization switch.
- a microprocessor is also provided in the label as well as an internal memory.
- the document DE4138131 describes a smart card with microprocessor, display screen and integrated memory powered by a solar collector. Communication between the card and an external read / write unit is contactless, for example by optical, capacitive or inductive transmission.
- the microprocessor, memory, display and solar energy sensor are physically connected inside the card by conductors.
- the document DE19604206 describes an intelligent portable object for the transmission of secure data.
- This smart portable object has a plastic card body, the size of a credit card. In a part of the card is housed a keyboard, with the function keys. Under the keyboard, galvanic conductors connect rows and columns together in a matrix to a control unit.
- the smart portable object is also equipped with an antenna, embedded in the body.
- Document US4874934 describes a smart card which consists of a central processing unit, data and program memories, as well as a display driver constituted by a chip. The components of the card are physically connected.
- intelligent contactless portable objects comprising a contactless communication interface capable of transmitting and / or receiving data by inductive coupling with a station.
- the contactless communication interface includes an antenna coil connected to a capacitor, an integrated circuit such as a chip or another component.
- Contactless intelligent portable objects have a peripheral circuit such as a display and a chip connected to this peripheral circuit.
- the chip operates identification and / or authentication functionalities, called “central” or “main” compared to the so-called “peripheral" display function.
- peripherals for example displays
- the implementation of connections between the chip and the device harms the cost of production of intelligent portable objects.
- the invention aims to remedy these drawbacks, and is defined in the claims. Thanks to the invention, the data exchanged between the peripheral circuit and the central circuit all pass through the station, which makes it possible to remove the connection between the peripheral circuit and the central circuit. This results in a simple and inexpensive installation of the peripheral circuit.
- Other characteristics and advantages of the invention will appear in the description of examples which follows.
- Figure 1 is a schematic view of a transponder with two contactless communication interfaces according to the invention
- FIG. 2 schematically illustrates an intelligent portable object according to the invention, capable of communicating without contact and equipped with a display
- FIG. 3 schematically illustrates a contactless intelligent portable object equipped with an integrated circuit forming a chip, a contactless circuit forming a display and a contactless integrated circuit forming a keyboard according to the invention.
- an intelligent portable object 2 comprises a contactless communication interface 4 which comprises an antenna coil L1 connected to an integrated circuit 6 called a chip.
- This chip 6 operates identification and / or authentication functionalities, called "central" or "main”.
- intelligent portable object should be understood here to mean any device or device capable of operating detection or communication using an electromagnetic field. These are, for example, smart cards, electronic labels or the like.
- This intelligent portable object 2 includes another contactless communication interface 8 which includes another antenna coil L2. Two pads 10 and 12 of the antenna coil L2 are connected to an integrated circuit 14 performing a peripheral function. We therefore speak of peripheral 14.
- This peripheral 14 is in the figures, a display peripheral. In other embodiments, the peripheral 14 is a keyboard, a sensor, for example a biometric sensor, a light-emitting diode or the like.
- This peripheral 14 operates so-called “peripheral” functionalities, here visualization, with respect to the identification and / or authentication functionalities, called “central” or “main” functionalities of the chip 6.
- the intelligent portable object 2 is capable of communicating without contact or remotely with a reader or station 20 comprising an antenna 22.
- station 20 is a transmitter / receiver device provided with an antenna which creates an electromagnetic field at a given frequency.
- the antenna 22 of the station device 20 makes it possible to modulate the electromagnetic field and to measure variations in this field.
- the antenna 22 of the station 20 generally comprises one or more coils. Inductive coupling between object 2 and station 20 is carried out when this object 2 is at a given distance, called "proximity" from station 20. According to objects 2 and stations 20, this distance is of the order of a few millimeters to a few meters.
- the circuit 14 here includes a display area 16. This circuit 14 is here able to be supplied by the current induced in the coil L2 when the coil
- L2 is in inductive coupling with the antenna 22 of the station 20.
- the circuit 14 is also able to extract from this induced current, information intended to be displayed.
- the induced current comes from an electromagnetic field emitted by the station 20, for example a badge reader or a smart card reader.
- the intelligent portable object 2 is a smart card in the IS07816 contactless or mixed format, that is to say with a contact interface and a contactless interface.
- the mixed card cooperates with a reader (not shown) having a contact communication interface as well as a contactless communication interface.
- the resonant circuits formed by the first communication interface 4 and the second communication interface 8 are chosen so that they are tuned to frequencies close to one another, and that the frequency resulting from the coupling of the two coils L1 and L2 is adapted to the frequency required by the station 20.
- the device 14 is, according to the examples, a contactless display or a standard commercial display fitted with a control device (driver) with data exchange protocol via a serial link. In the latter case, an adaptation circuit is used to produce, from the current induced in the coil L2, all of the signals necessary for the operation of this peripheral 14. According to another example of the invention, the peripheral 14 performs an input keyboard function. This peripheral 14 forming a keyboard is also of the contactless type. This device 14 is able to communicate with the contactless reader 20 via an electromagnetic field in the same way as the chip 6 or the display mentioned above, and according to the same principle, namely a modulation of the electromagnetic field.
- Such a device 14 forming a contactless keyboard makes it possible in particular to remove keyboards on terminals such as the station 20.
- this device 14 participates in reducing the costs of the system and especially in increasing the security of the stations 20; in fact, the keyboard of a station 20 which has a direct interface with the outside world, is a privileged entry point for outside attacks.
- the contactless peripheral 14 is provided with electric current, that is to say "self-powered" by the induced current, the entry of a secret code is more difficult to spy on than that which is carried out on a keyboard. station 20.
- the intelligent portable object 2 comprises several peripherals, such as a contactless keyboard and a display.
- a contactless keyboard and a display such as a contactless keyboard and a display.
- two contactless peripheral circuits are integrated into the intelligent portable object 2, one forming a display 14, the other forming a keyboard 30.
- This circuit forming a contactless keyboard 30 comprises several keys 32.
- This keyboard 30 has a resonant circuit able to send to the reader or station 20 information corresponding to the key 32 pressed by the user.
- a contactless light-emitting diode (not shown) associated with another resonant circuit makes it possible, by visualization, to confirm that all of the peripheral circuits without contact in the intelligent portable object 2 are supplied by the electromagnetic field.
- the station 20 exchanges data with the integrated circuit forming a chip 6 by means of amplitude modulation, according to a protocol conforming to a standard in force, for example the ISO 14443 standard.
- the exchanges with the circuits forming the contactless keyboard 30, the contactless display 14, the contactless light-emitting diode are effected by using an amplitude modulation having characteristics different from those of the modulation between the chip 6 and the reader 20 so as to allow the selection by the reader of the targeted contactless peripheral element.
- this display 14 only requires the reception of data.
- a low frequency pulse generator for example of a few kHz and the number of these pulses corresponds to the key pressed code.
- the reader 20 then detects these pulses which modulate the antenna coil 22 of the reader 20.
- the reader 20 deduces therefrom the pulses thus triggered.
- Other more sophisticated selection modes can be used in order to implement the selection of the contactless peripheral element.
- anti-collision selection mechanisms can be used, such as anti-collision systems by selection of serial numbers.
- the invention it is possible to use a protocol according to which the communications between the intelligent portable object 2 and the station 20 are carried out via the station, so that if a data item is to be displayed, it must be sent by the station 20 to the display 14 via the electromagnetic field.
